ABSTRACT
Introducción: Los linfomas gástricos primarios representan menos del 5% de los linfomas no Hodgkin (LNH). La gran mayoría de linfomas gástricos primarios son linfomas de células B de alto grado. Los linfomas gástricos primarios de células T son muy raros y usualmente se asocian a infección por HTLV-1 en regiones endémicas. Material y método. Describimos el caso de una paciente mujer de mediana edad que se presentó con neumoperitoneo debido a ulcera gástrica perforada, síndrome consuntivo y lesiones cutáneas y orales. Resultados. La histopatología e inmunohistoquímica confirmaron linfoma gástrico primario de células T con compromiso cutáneo. La serología para HTLV-1, virus del Epstein-Barr y VIH fueron negativas. Conclusión. La finalidad de este reporte es dar a conocer esta forma de presentación sumamente rara de linfoma gástrico primario.
Background: Primary gastric lymphomas account for less than5%ofnon-Hodgkinlymphomas(NHL).Thevast majority of primary gastric lymphomas are high-grade B-cell lymphomas. Primary gastric T-cell lymphomas are very rare and are usually associated with HTLV-1 infection in endemic regions. We describe Material and methods.the case of a middle-aged female patient who presented with pneumoperitoneum due to a perforated gastric ulcer, wasting syndrome, and skin and oral lesions. . Results: Histopathology and immunohistochemistry confirmed primary gastric T-cell lymphoma with skin involvement. The serologyfor HTLV-1,Epstein-Barr virus and HIVwere negative. The aim of this report is to present Conclusion: this extremely rare presentation of primary gastric lymphoma
ABSTRACT
Tuberculous meningitis (TBM) is a medical emergency: it is the most severe, lethal and disabling clinical form of tuberculosis. We report the case of a 44-year-old woman who had undergone a clandestine abortion six weeks before admission. One week later, she had abnormal vaginal discharge. Three weeks prior to admission, headache, hyperpyrexia and mental alteration were added. At admission, a transvaginal ultrasound showed abnormalities of the uterine cavity. Sepsis and endometritis were diagnosed, and a hysterectomy was scheduled. During preoperative evaluation, meningeal signs were found. The first lumbar puncture (LP) showed a lymphomononuclear pleocytosis, hypoglycorrhachia and hyperproteinorrachia. After five days treatment with ceftriaxone, vancomycin and dexamethasone, only partial recovery occurred. A second LP showed AFB and PCR confirmed Mycobacterium tuberculosis. The histopathology of endometrial biopsy confirmed endometrial tuberculosis. Therapeutic response to anti-tuberculous treatment and corticosteroids was excellent. No other cause of immunosuppression apart from pregnancy was found. To the best of our knowledge, this is the first report of TBM secondary to endometrial tuberculosis and highlights an unusual clinical scenario in which severe and disseminated forms of TB could be present. TBM during and after pregnancy is rare, but compared with TBM in non-pregnant women, it has a poorer prognosis. Early diagnosis and treatment can be lifesaving in this life-threatening disease.
